Affiliate Referrals - Advanced Settings

I love that you guys can 'sort out' the traffic from a domain - thus potentially increasing our opportunities to promote with impunity.

There's only one glitch. The 'Affiliate Advanced Settings' section only allows me to list one primary domain.

I run two domains for my main web-business.

I run up to three community sites that will be developing in the next year.

I have a fan page with almost 50K people who'd benefit from your offerings.

How can we implement even more 'Affiliate Advanced Settings' listing all of our web properties? Possible?

Cheers, Lee
